id summary reporter owner description type status component version resolution keywords cc guest host 12851 High cpu-load (up to 100%) on idle Sworddragon "My host is Linux 3.13.6 x86_64 and the guest is Windows XP SP3 32 bit with all current updates installed. The guest additions with experimental 3D support are installed too. If the Windows XP guest is booted up and reached the idle state (0-1% cpu-load in the task manager) I'm noticing that on my Linux host the cpu-load is constantly at ~15% of one core (AMD Phenom II X6 1045T). If I'm booting up the Windows XP guest into the safe mode and it reached the idle state the cpu-load on my Linux guest goes even up to the maximum (~600%/600%)." defect reopened other VirtualBox 4.3.6 Windows Linux
